Abstract

Proper management and prevention of dysphagia are urgently needed in acute care of stroke patients in Korea. However, no highly sensitive and accessible nurse-led screening tools have been validated within the Korean settings. The purpose of this study was to validate a screening tool led by nurses to identify dysphagia and aspiration risks among acute stroke patients. Registered nurses (RNs) screened 131 residents from a university hospital in South Korea using the Korean version of the Standardized Swallowing Assessment (K-SSA). Results were validated against those from the Gugging Swallowing Screen (GUSS). Compared to results from the GUSS, with 9- and 14-point cutoffs, the K-SSA had a sensitivity of 0.80 and specificity of 0.90 [95% CI 0.806, 0.992] for screening dysphagia and 1.00 sensitivity and 0.94 specificity [95% CI 0.862, 1.000] for screening aspiration risks. The K-SSA demonstrated excellent sensitivity and specificity for screening individuals at risk of dysphagia and aspiration when led by RNs for acute stroke patients.
